Product analysis
Mega D-3 5000 IU & MK-7 180 mcg supplies nutrients that support normal bone and mineral balance. Its identified MK-7 and low serving cost support its appeal.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality70
The identified MK-7 is a favorable vitamin K form. Vitamin D’s source is named, but there is not enough information for a comparative quality judgment.
Ingredient Transparency100
Both nutrient amounts and their forms or sources are disclosed. That makes the combination easier to compare with other D and K supplements.
Value For Money70
The serving cost is low for the MK-7 supplied. Vitamin D’s value cannot be judged separately with confidence.
Customer Satisfaction97
Customer ratings are very positive. The large number of ratings offers a broad view of sentiment, without proving effectiveness.
Product Focus80
The clearest purpose is nutritional support for bone and mineral balance. Findings for artery flexibility are limited to particular groups, and an extra benefit from combining D and K is not established.

Goals
Vitamin D and vitamin K supply nutrients relevant to bone and mineral balance, with their value depending on low intake rather than added benefit above adequate intake. The supplied information does not establish extra benefit from combining them or from the MenaQ7 form. Calcium is claimed in the stored label text, but its presence and amount remain unconfirmed and it was not counted.

Effective doses
Vitamin D supports calcium absorption and normal mineralization when intake or status is low. The identified MK-7 provides a connection to limited bone-density findings in postmenopausal women at 180 mcg daily, although results are mixed and fracture prevention is unestablished. The high vitamin D serving does not prove greater benefit. Calcium presence and amount remain unresolved despite the supplied label claim, limiting the partner finding.

Effective doses
Vitamin K as the declared MenaQ7 MK-7 preparation has limited support for arterial-stiffness changes in healthy postmenopausal women. The 180 mcg serving receives full saved amount recognition, without establishing cardiovascular-event prevention. Vitamin D’s 125 mcg serving also receives saved amount credit, but supplementation has not demonstrated routine cardiovascular prevention, and no additional benefit from combining D and K is established.

MenaQ7 vitamin K2 has narrow findings for selected arterial-stiffness measures in postmenopausal women after three years of use. The 180 mcg serving matches the daily study amount. Vitamin D can support muscle function when deficiency is corrected, but the larger amount here does not imply greater benefit in replete adults or an added benefit from combining D3 with K2.

Effective doses
Vitamin K as MK-7 has limited evidence for improving selected measures of arterial stiffness in postmenopausal women. This serving supplies 180 mcg, matching the daily amount in the supplied three-year trial. Those marker changes do not establish prevention of cardiovascular events, and vitamin D does not establish an added cardiovascular effect or D3/K2 synergy.
